Operations of the information processing system 1 are described next with reference to FIGS. 5, 6A, and 6B.

FIG. 5 is a sequence diagram to illustrate the operating procedures of the information processing system 1 in the present embodiment. FIG. 5 illustrates the steps in the coordinated operation of the server apparatus 10, the vehicle 12, and the terminal apparatus 13. The steps pertaining to the various information processing by the server apparatus 10, the vehicle 12, and the terminal apparatus 13 in FIG. 5 are performed by the respective controllers 23, 33, 43. The steps pertaining to transmitting and receiving various types of information to and from the server apparatus 10, the vehicle 12, and the terminal apparatus 13 are performed by the respective controllers 23, 33, 43 transmitting and receiving information to and from each other via the respective communication interfaces 21, 31, 41. In the server apparatus 10, the vehicle 12, and the terminal apparatus 13, the respective controllers 23, 33, 43 appropriately store the information that is transmitted and received in the respective memories 22, 32, 42. Furthermore, the controllers 23, 33, 43 accept input of various information by the respective input interfaces 25, 35, 45 and output various information by the respective output interfaces 26, 36, 46.

In step S500, the vehicle 12 transmits positional information and vehicle information to the server apparatus 10. The vehicle information includes, for example, identification information, the model, the type, and the specifications of the vehicle. The vehicle information may include information about the owner or driver. Next, in step S502, the server apparatus 10 transmits the positional information and the vehicle information for the vehicle 12 to the terminal apparatus 13. The terminal apparatus 13 then transmits a usage request for the vehicle 12 to the server apparatus 10. The usage request is generated and transmitted to the server apparatus 10 by the user operating the terminal apparatus 13. The usage request includes information identifying the vehicle 12 that the user wishes to use and information such as the boarding point and the boarding time.

In steps S500 to S504, the user of the terminal apparatus 13 uses, for example, the terminal apparatus 13 to access a portal site, for members of the car sharing service or the like, provided by the server apparatus 10. The portal site displays, for example, the type of vehicle, position, and the like of one or more of the usable vehicles 12. The user selects the vehicle 12 that the user wishes to use and also inputs the boarding point, boarding time, the user's member ID, and the like to the terminal apparatus 13. For example, as illustrated in FIG. 6A, the terminal apparatus 13 displays a map 6 that includes the position 60 of the vehicle 12 and the current position 63 of the terminal apparatus 13. The user inputs the selection of the vehicle 12 and the designation of the boarding point 62 by, for example, tapping on the position 60 of the vehicle 12 and the desired boarding point 62 on the map 6. The user may also provide input by a sliding movement on the map 6, for example, to designate a boundary 64 of the reference range for displaying the image captured by the vehicle 12. The reference range is any appropriate range of the distance from the boarding point 62. In a case in which the boundary 64 of the reference range is not designated, a range with a freely set initial value (for example, several hundred meters) may be used as the reference range. The terminal apparatus 13 generates a usage request based on the information identifying the selected vehicle 12 and the inputted information and transmits the usage request to the server apparatus 10. Information identifying the terminal apparatus 13 is included in the usage request.

In step S506, the server apparatus 10 transmits a usage confirmation request to the vehicle 12 identified in the usage request. The information contained in the usage request is included in the usage confirmation request. The vehicle 12 displays information to the driver on the boarding point and boarding time, for example. The driver inputs the usage confirmation to the vehicle 12. The usage confirmation includes information indicating whether the usage request will be accepted. For example, the driver inputs the usage confirmation by tapping a button indicating acceptance of the usage request. In step S508, the vehicle 12 transmits the usage confirmation to the server apparatus. Upon receiving the usage confirmation, the server apparatus 10 performs steps S510 and S512. In a case in which one or more of the components of the vehicle 12 illustrated in FIG. 3 is configured as a terminal apparatus having information processing functions, and the terminal apparatus is carried by the driver, steps S506 and S508 may be performed by the terminal apparatus.

In step S510, the server apparatus 10 transmits usage information to the terminal apparatus 13. The usage information indicates that the usage request has been accepted. The terminal apparatus 13 displays the usage information to the user. Once the user confirms acceptance of the usage request, the user travels to the boarding point carrying the terminal apparatus 13.

In step S512, the server apparatus 10 transmits a travel start instruction to the vehicle 12. Once the vehicle 12 receives the travel start instruction, the vehicle 12 starts traveling from its current position toward the boarding point.

Steps S514 to S522 are performed in any appropriate cycles (for example, in cycles of several milliseconds to several seconds).

In step S514, the vehicle 12 transmits a captured image and positional information to the server apparatus 10. The captured image is a captured image of the surroundings of the vehicle 12 and is obtained by, for example, capturing an image of the scenery/subjects in the travel direction of, to the sides of, or behind the vehicle 12. The captured image may be a moving image captured at any appropriate frame rate (for example, 30 FPS). Here, the cycles for image capture, positional information acquisition, and transmission of the captured image and positional information may be different.

Upon receiving the usage information, the terminal apparatus 13 transmits positional information to the server apparatus 10 in step S516. Here, the server apparatus 10 aborts the subsequent steps in a case in which the position of vehicle 12 and the position of the terminal apparatus 13 are both the same as the boarding point.

In step S518, the server apparatus 10 determines the captured image to be transmitted. The server apparatus 10 determines the captured image to be transmitted based on the positional information transmitted from the vehicle 12 together with the captured image. The positional information transmitted from the vehicle 12 together with the captured image generally corresponds to the point where the image was captured. Here, for example, the server apparatus 10 determines the captured image transmitted together with the positional information as the captured image to be transmitted on the condition that the position of the vehicle 12 indicated by the positional information is within a reference range from the boarding point. Alternatively, in a case in which the positional information transmitted from the terminal apparatus 13 and the positional information transmitted from the vehicle 12 match, the server apparatus 10 may determine the captured image transmitted together with the positional information as the captured image to be transmitted.

In step S520, the server apparatus 10 transmits the determined captured image and the positional information transmitted from the vehicle 12 together with the captured image to the terminal apparatus 13. At this time, the server apparatus 10 may transmit the captured image and the like on the condition that the position of the terminal apparatus 13 is within the reference range from the boarding point.

In step S522, the terminal apparatus 13 outputs the captured image and positional information transmitted from the server apparatus 10. The terminal apparatus 13 displays a map 6, as illustrated in FIG. 6B, for example, that includes the position 60 of the vehicle 12, the current position 63 of the terminal apparatus 13, and the boarding point 62. The boundary 64 of the reference range may be displayed on the map 6. Here, the position 60 of the vehicle 12 is within the reference range, and therefore the terminal apparatus 13 displays the captured image 61. The captured image 61 is, for example, an image of the scenery in the travel direction of the vehicle 12. The captured image 61 is a moving image. The captured image 61 may be superimposed on the map 6, as in FIG. 6B, or may be displayed on a portion of the display other than the map 6.

According to the present embodiment, when moving to the boarding point, the user can view the captured image, on the terminal apparatus 13, of the surroundings of the vehicle 12 that is heading to the boarding point. Even if the user is unfamiliar with the boarding point, the user can identify the boarding point more easily than with a map and can efficiently meet up with the vehicle 12.

Since the degree of contribution to the identification of the boarding point is relatively low during a display of captured images of points more than a certain distance from the boarding point, unnecessary processing and information communication can be omitted by displaying only images captured within the reference range. Furthermore, when the user moves to the boarding point, the degree of contribution to the identification of the boarding point is relatively low upon comparing the captured image with the scenery at a point more than a certain distance from the boarding point. Therefore, by requiring the terminal apparatus 13 to be within the reference range as a condition for captured image output, the user can more easily compare the captured image with the surrounding scenery. The boarding point can thereby be identified more reliably.

Alternatively, in a case in which the user is moving to the boarding point, and the user moves by a point that the vehicle 12 has passed, i.e., in a case in which the positional information acquired by the server apparatus 10 from the vehicle 12 matches the positional information for the terminal apparatus 13, the captured image that was captured at that position is transmitted to the terminal apparatus 13 for display. With this configuration, the user can more reliably identify the boarding point by comparing the captured image with the surrounding scenery. Furthermore, the terminal apparatus 13 may display the trajectory of the position of the vehicle 12, and the captured image for a point selected by the user on the trajectory may be displayed. For example, the user can select any point on the trajectory of the vehicle 12 on the map 6 with a tap operation or the like, and based on the selection, the server apparatus 10 can transmit the captured image of the selected point to the terminal apparatus 13. This configuration can improve user convenience.

In the above embodiment, the server apparatus 10 selects the captured image to be transmitted to the terminal apparatus 13 based on the positional information from the vehicle 12. However, the server apparatus 10 may transmit information on the reference range to the vehicle 12 together with a travel start instruction, and the vehicle 12 may determine whether to perform or abort imaging or transmission of the captured image based on the current position of the vehicle 12 itself. In other words, when the current position of the vehicle 12 itself is within the reference range, the vehicle 12 captures an image and transmits the captured image to the server apparatus 10. Alternatively, the vehicle 12 periodically captures images and transmits a captured image to the server apparatus 10 when the current position of the vehicle 12 itself is within the reference range. With this configuration, concentration of the processing load on the server apparatus 10 in a case in which the server apparatus 10 manages a plurality of vehicles 12 can be avoided.

In the above embodiment, a processing/control program that specifies operations of the vehicle 12 and the terminal apparatus 13 may be stored in the memory 22 of the server apparatus 10 or in the memory of another server apparatus and be downloaded onto each apparatus via the network 11. The processing/control program may also be stored on a non-transitory recording/storage medium readable by each apparatus, and each apparatus may read the program from the medium.

Accordingly, such modifications and revisions are included within the scope of the present disclosure.
